JOHN H. HISE, LOS ANGELES, CALIFORNIA, ASSIGNOR, BY MESNE ASSIGN- MENTS,OF ONE-HALF TO GEORGE R. SI-IATTO, OF SAME PLACE.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 501,249, dated July 11,1893.

Application filed September 21, 1892- Sarial No. 446,472- (No model.)

To all whom it may concern.-

Be it known that 1, JOHN H. HIsE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Improvement in Refrigerators,of which the following is a specification.

My invention relates to the construction of refrigerators and coolingrooms, 850.

The object of my invention is to increase circulation, prevent mustinessand bad odors within the refrigerator and to cause the refrlgerator topreserve perishable articles such as meats, berries, 850., and to removeslight taint from meat, &c; also to allow articles of different odorsand aromas to be kept in the same cooling chamber without injury to anyof them.

My invention consists in a refrigerator comprising the combination of anice chamber arranged at the upper portion of the refrigerator, closedthroughout except an air inlet at the top and an air and drip outlet atthe bottom, and having its floorarranged to allow the Water from themelting ice to pass there through; the cooling chamber arranged in thelower portion of the refrigerator and having an open drip pan at thebottom thereof; an ascending warm air draft flue communieating betweenthe top of the cooling chamber and the top of the ice chamber; an upperopen drip pan arranged bet-ween the ice chamber and the cooling chamberat such a distance-below the ice chamber as to provide a drip chamber ofmaterial depth so that the water falling from the ice chamber willcreate a downward draft of air from the ice chamber toward the bottom ofthe drip chamber; a cold air discharge communicating between the rear ofthe drip chamber and the rear top of the cooling chamber; an open lowerdrip pan arranged at the bottom of the cooling chamber, and the dripdischarge arranged to discharge the drip from the upper drip pan intothe'cooling chamber, and therethrough into the lower open drip pan.

My invention more broadly stated also consists in a refrigerator havingan open drip pan arranged between the cooling chamber and the icechamber to receive the drip from the melting ice, and also having anopen drip pan arranged at the bottom of the cooling chamber; adrip-discharge arrangedto discharge from the upper drip pan into thelower open drip pan, the air passage leading from above the upper drippan into the cooling chamber, the air passage leading from the coolingchamber and opening into the top of the ice chamber, and the air anddrip passage leading through the bottom of the ice box into the upperdrip pan.

My invention also comprises other features and combinations hereinafterset forth.

The accompanying drawings illustrate my invention.

Figure 1 is a vertical section from front to rear of a cooling room foruse of butchers, &c. Fig. 2 is a vertical longitudinal section of suchcooling room on line 00x looking toward the rear. Fig. 3 is a section ofthe front receptacle showing details of a device for counterbalancingthe lid of the front receptacle and closing the passage between thefront receptacle and the main cooling room when the lid of the frontreceptacle is raised, so that there will be no unnecessary escape ofcold air from the cooling room when the front receptacle is opened. Fig.4 illustrates the construction of the upper water pan and the ceiling ofthe cooling chamber. Fig. 5 is a detail of the over flow.

A A, &c., indicate the insulated Walls of the refrigerator or coolingroom.

B indicates the ice chamber in the upper portion thereof.

0 indicates the cooling chamber.

D indicates the ascending warm air draft flue at the front side of therefrigerator communicating between the top of the cooling chamber andthe top of the ice chamber.

E is an insulated wall interposed between the draft flue D and the icechamber B, the drip chamber or space F, drip pan G and air chambers H.

I is the cold air discharge communicating between the rear of the dripchamber and the top of the cooling chamber. The upper drip pan G isarranged beneath the slatted floorJ of the ice chamber at such adistance therebeneath that the water falling from such slat- I00 in thedrip pan and will also act upon the air to impel it downward, thus toassist in forcing the air out of the drip chamber through the rear coldair discharge passage I. The over-flow L is arranged to discharge thewater from the drip pan when the water has risen therein to about oneinch and a half. The distance between the slatted floor J of the icechamber and the su rface of the water, when the drip pan is properlyfilled is about a foot. It is to be understood that'this distance may bevaried within the judgment of the constructor. The greater the distancethe greater will be the velocity of the water and the circulation ofairthrough the cooling chamber.

G is a water pan or receptacle arranged beneath the slatted floor N ofthe cooling chamber.

0 is the drip pipe leading from the upper over-flow L and discharging atthe rear side of the cooling chamber at such a distance below the lowerpan as to allow the water to gain a desirable velocity after itsdischarge from the end of such drip pipe and before it reaches thesurface of the water within the lower wa ter pan and to also cause anagitation and splashing of the water within the lower water pan.

It will be understood by those acquainted with the construction ofrefrigerators that the domestic refrigerators will not be provided withthe front receptacle P which is shown in the drawings, but that therefrigerator will be provided at its front side with a suitable door togive access into the cooling chamber.

Q indicates a partition between the front receptacle P and the maincooling chamber.

R indicates an opening at the bottom through such partition to allow thecool air to flow from the cooling chamber into the front receptacle.

S indicates an opening arranged at the top of the partition above theopening R to allow the warm air from the front receptacle to flow intothe main cooling chamber.

T indicates a vertically reciprocating valve arranged to close theopenings R and S.

U indicates the lid of the front receptacle.

V is a curved valve operating lever fixed to the rear of such lid andprojecting backward therefrom and connected with the valve T by theconnecting rod WV, which is hinged at one end to the valve and at theother end to the valve operating lever, the several parts being soarranged that when the lid is raised as indicated in dotted lines inFig. 8 the valve will be forced down to close the openings R and S, thusto prevent the passage of air from the cooling chamber when the frontreceptacle is open. There is free passage beneath the partition to allowthe water in the lower water pan to pass freely from the rear of thecooling chamber to the front receptacle whence it is discharged throughthe lower overflow L. By this arrangement the water is caused to flowthrough the refrigerator or cooling room in the direction in which thecooled air flows. The ascent of the warm air is at the front part of therefrigerator directly from the front side of the cooling room andrefrigerator, which is the side most exposed to the admission of heat.The insulated wall between the draft flue D and theice prevents the airin the draft fl ue from becoming cooled until it has come in contactwith the top of the ice. The air chambers H arranged be tween theceiling of the cooling chamberand the upperdrip pan insulate the drippan from the cooling chamber and prevent the condensation of moisturewhich might occur on the ceiling of the cooling chamber if it were notinsulated or properly separated from the bottom of the drip pan.

a indicates air passages in the rear walls of such air chambers to allowcirculation of air between the outside and inside of such chambers.

My refrigerator is provided with an improved refrigerator over-flowconsisting in the combination of a plug seat Z) inserted in and openingthrough the bottom of the water pan or drip pan and an over-flow plug 0arranged to fit in the plug seat to close the same water tight andprovided with an upwardly extending over flow tube (1 of a height equalto the depth of water desired in the drip or water pan and openingdownward through the plug so that when the water rises within the drippan or water pan to the top of such tube d the water will escape throughthe tube and when it is desired to empty-the drip pan or water pan thesame may be accomplished by withdrawing such plug, thus allowing thewater to flow directly out through the open plug seat I). The floors ofthe drip pan and water pan are arranged to slope sufficiently towardtheir respective plug seats or discharges b to drain the water into suchdischarge opening but no attempt has been made to illustrate suchconstruction for the reason that the same is Well understood and doesnot require illustration and the scale of the drawings is too small toallow such construction to be indicated as the slope is very slight.

Y and Z indicate doors into the ice and cooling chambers respectively.

In practice the ice is placed upon the slatted floor of the ice chamberwith sufficient space between the blocks to allow air to pass downwardbetween such blocks, and materials to be cooled are placed in thecooling chamber in the customary manner, the heated air within thecooling chamber being forced to the top of the refrigerator by the coolair which falls from the ice, rises through the draft flue D and passesover and upon the ice blocks and thus becoming cooled falls downwardbetween the ice blocks. The water formed from the ice melted by the heatfrom such air flows downward along the sides of the cakes of ice and byits friction upon the air. assists in car rying the air downward andwhen such water has reached the bottom of the ice cakes or the ICCbottom-of the slats of the floor upon which such cakes rest, it forms indrops and passes thence down into the drip pan carrying with has notbeen absorbed by the water while the air was passing over the ice anddownward be,- tween the cakes of ice; the air therefore issues from therear discharge I in a purified and comparatively anhydrated conditionand passes on downward through the cooling chamber toward the front partof the same, absorbing-from the materials within the cooling chamber theheat and moisture which such materials may give 0% and when the air thusbecomes heated and expanded it ascends again through the draft fiue D,and the circuit is repeated. The discharge of the drip water from thedrip pipe 0 causes a downward flow of air at the rear of the coolingchamber to beneath the slatted floor and the air is thus caused tocirculate over the water in such lower water pan. The air which comesinto contact withthe water in the drip pan is warmer than such water andthe water will attract therefrom particles of moisture which maybecarried thereby and will at the same time remove odors and purify theair. The splashing of the water at this point also assists in purifyingthe air as above stated with relation to the upper drip pan.

The attraction of the water for odors and impurities of the air is verygreat at the time the water is expandingunder the influence of thecurrents of warm air which pass over the ice and through the dripchamber and the odors are so perfectly removed from the air that thedifferent articles which might be.

contaminated by interchange of flavors, odors or aroma may be keptwithout injury within- Where such faucet is used it is necessary,

, from time to time, to drain the water off from water sufficiently freefrom accumulated im-- purities. g

It isimportant that the ice chamber be closed at the sides and that itsair inlet be at the topof such chamber and the airoutlet at the bottomthereof through the ice rack or slattedfloor above the drippan, so thatthe air will be driven'downward by the force of the drip and will becaused to pass downward between the cakes of ice and will be driven downand caused to strike upon the water in the drip pan; the air outlet Ifrom the drip pan being so arranged as to increase or to facilitate thiseffect. It is also 'important that the ice in the ice chamber shall notbe allowed to become exhausted while water remainsin the waterreceptacles, for the rea-' son that in time the water will throw off impure vapors which will taint the refrigerator and its contents and theinside of the refrigerator will become moist and moldy.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A refrigerator comprising the combination of an ice chamber arrangedat the'upper portion of the refrigerator, closed throughout except anairinlet at the top and an air and drip outlet at the bottom, and havingits floor arranged to allow the water from the melting ice topasstherethrou'gh; the cooling chamber arranged in the lower portion ofthe refrigerator and having an open drip pan at the bottom thereof; anascending warm air draft flue communicating between the top of thecooling chamber and the top of the ice chamber;. the upper open drip panarranged between the ice chamber and the cooling chamber at such adistance below the ice chamber as to provide a drip chamber of materialdepth so that the water falling from the ice chamber will create adownward draft of air from the'ice chamber toward the bottom of the'drip chamber; a cold air discharge. communicating between the rear-ofthe drip chamber and the rear top of the cooling chamber; the open lowerdrip pan arranged atthe bottom of the cooling chamber, and the dripdischarge arranged to discharge the drip from the upper drip pan intothe cooling chamber and therethrough into the loweropen drip pan.

2. A refrigerator having an open drip pan arranged between the coolingchamber and the ice chamber to receive the drip from the her and thefront receptacle; the combination set forth of a vertical partitionarranged between the front receptacle and the cooling chamber andprovided at its bottom with the cool air opening and at its top with thewarm air opening; the lid of the front receptacle; the verticallyreciprocating valve arranged to close the warm and cool air openings;the
